How is a linked list different from an array in terms of memory storage?
The memory locations of a linked list are not contiguous, unlike an array.
What is the purpose of the head node in a linked list?
What is the purpose of the head node in a linked list?
The head node points to the first node in the list and is used to access the linked list.

Study Notes
Linked List Overview
- Linked list stores data sequentially but with non-contiguous memory locations
- Unlike arrays, linked lists can store data of different data types
- Node in a linked list consists of Data and Next Pointer components
- Data component holds the actual value associated with the node
- Next Pointer component stores the memory address of the next node in the sequence
- The linked list is accessed through the head node, which points to the first node
- The last node in the list points to NULL or nullptr, indicating the end of the list
- The last node is known as the tail node
- Linked lists can be represented in memory using two arrays: INFO and LINK
- INFO[K] and LINK[K] contain information of an element and the next node respectively
- Representation of linked list in memory involves using two arrays: INFO and LINK
- Traversing a linked list is a common operation on linked list data structure
